Here's the setup:
You are creating a ruleset for a cinematic, high-action, swashbuckling game.
Each class has a Defense bonus that increases with level advancement.
The Vitality/Wound Point system will be used.
Armor will be treated as DR.
Design Goal: You want to lessen the reliance on armor, or at least make players think twice about wearing very heavy armor.
Option: How do you feel about armor giving a penalty to Defense, perhaps equal to its Armor Check Penalty?
Yeah, you have to balance armor against Defense. Both working together are too much. Now you are talking about a straight armor = DR system? You'll have very tough heroes, even applying the ACP.
Lets assume a standard campaign. Say 5th level. You could have a Fast Hero 5 with a defense of +5, lets say 16 dex for an AC of 18. Add a MW Chain shirt and you hero takes a paltry -1 to AC to pick up DR 4? I don't think you will lessen reliance on armor GJ, you'll increase it.
I think a better was is to cap the defense you can use to the max dex. Especially with armor as straight DR, this might work out better. Your fast hero will still wear armor until the mid levels, but the lightest he can get. Your stronger/slower heroes will have less Defense to sacrifice to wear heavier armor. A Tough Hero 5 with a Defense of 3, can use his enitre Defense using a breastplate, or only loses 1 with MW Banded Mail and gains DR6.
The fast hero will always shed his armor first, but all the heroes will shed armor as they gain levels, although I would expect some to hang on to a small Defense penalty to gain such great DR.
Have you considered Old One's armor provides half AC DR with the max dex limit? Makes for harder choices earlier on. But while it does keep ACs up, it keeps DR down. Thats the "look" hit more often for smaller damage in your system, or hit fewer times for more once you get hit.
I just don't see your design goal being met with the options you present. A low level strong, will get tagged every time, AC of what 12 a best, but if he has 8 DR, what low level threat will get through?
